Electronic Musical Instruments

What is the name of an old electronic addition that is purple and black for kids?

I am looking for a game that I used to play when I was little. It was an electric game that I used to play that had a middle button and four buttons on the outside. Each button represented the numbers 1-4 and had black dots to represent each number. I cant remember exactly what the game asked you to do, but I just remember it saying something like “one plus one is…” or “two plus two is…” You had to push the buttons that corresponded. A website would be great to see a picture of the game. Thanks!!
